SPECIFICATION forming part of Letters Patent No. 650,466, dated May 29, 1900.

Application filed December 30, 1899.I Serial No. 742,101. (N0 mOeJ To @ZZ whom it may' concern,.-

' Be it known that l, VIRGIL E. KERR, a citizen of the United States, residing at Falls Church, in the county of Fairfax and State of Virginia, have invented a new and useful Bedstead Attachment, of which thefollowin g is a specification.

This invention relates to bedsteads in gen eral, and while the principles involved may be applied to a bed of any style the invention relates specifically to and is particularly adpted for use in connection with iron-frame be s.

One object of the present invention is to provide a construction of bedstead in which the entire Slat-supporting frame will be yieldably supported and will thus sink in its entirety under the weight of the occupant of the bed instead of yielding only at points, as is the case with the ordinaryspring-beds.

A further object of the invention is to provide means for adjusting the height of the slats and correspondingly increasing the length of the path of movement of the slats and their support to compensate for increased weight upon the bed, an additional object of the invention being to permit inclining of the slats in order that the ends thereof next to the head may be raised and lowered with respect to the opposite ends, and vice versa.

In the drawings forming a portion of this specification, and in which similar numerals of reference designate like and corresponding parts in the several views, Figure 1 is a perspective view showing a complete bedstead constructed in accordance with the present invention. Fig. 2 is a vertical section of the lower portion of one of the posts of the bedstead, taken transversely of the bedstead and showing parts of the interior mechanism in elevation and illustrating also the connection of one of the Slat-supports and the loca-v tion of the slats thereon. Fig. 3 is a'transverse section of one of the end supports for the slats andshowing the end of an adjacent slat engaged therewith. Fig. 4 `is a transverse section of one of the foot-posts of the .bedstead and taken on a line just above the bers, the operative positions of these adj ustable members being indicated in dotted lines. Fig. 6 is a plan View showing the mutuallyadjacent ends of the supplemental s1atsup ports and a part of the support to which they are attached, the ends of the supplemental supports being shown as connected by pins passed through alining perforations therein.

Referring now to the drawings, the bedstead of the present invention comprises headposts 5`and 6 and foot-posts 7 and 8, each of which consists of a tube of suitable length. The head-posts 5 and 6 are connected by means of cross-braces 9 and l0, which have attached thereto the usual spindles 11, the foot-posts having also connecting-braces 12 and 13, lto which are secured spindles 14, the posts being thus rigidly connected to form a head and a foot.

At a suitable distance from the lower end of each post is formed a flange 15, the outer faces of which are flattened and lie at right angles to each other. Secured to one fiat outer face of each of the blocks 15 of the posts 7 and Sis a foot-rail 16, While to the adjacent outer faces of these iianges are secured side rails 17 and 18, having their opposite ends secured to the corresponding faces of the flanges upon the head-posts 5 and 6. Secured also to the flanges of the head-posts is a headrail 19, these rails and posts being rigidly Vsecured together to form the frame proper of thebedstead. j

In the adjacent sides of the foot-posts '7 and 8 are formed slots 20, which extend longitudinally thereof and terminate at their upper ends substantially in the plane of the upper surfaces of the rails of the bedstead. These slots extend downwardly to points adjacent the lower ends of the posts, and they lead into the interior of the posts. Similar slots 21are formed in the inner faces of the head-posts 5 and 6. Y

The lower end of each of the posts 5, 6, 7, and S is interiorly threaded, as shown at 22 in Fig. 2 of the drawings, and with these threads is engaged the stem 23 of a plate 24, upon which is pivotally mounted a caster 25. This stem 23 acts as a plug for the lower end of the post and also forms a seat upon which the side rails.

rests the lower end of an interiorly-threaded tube 26, which is disposed withinv the post, and While iittingsnugly therein may be readily applied and removed.

The tube 26 forms one member of ascrewjack, of which the other member isformed by a screw 27, which may be adjusted with respect thereto to cause its upper end to lie at different points of the inclosure of the posts.

Adjacent the upper end of the screw 27 is a liange 28, beyond which an unthreaded portion 29 of the screw extends, and this iiangc 2S receives directly the lower end of ahelical spring 30, vwhich encircles the Unthreaded portion 29, this spring extending upwardly within the posts and being movable with the element 27 of the jack. j Slat-supports 31 are disposed with their ends projected inwardly through the slots20 and 2l, respectively, these Slat-supports being disposed one adjacent the head-rail 19 and another adjacent the foot-rail 16 and parallel therewith. Upon the lower faces of the end portions of the Slat-supports are formed lugs 32, which enter the inclesu res of the upper ends of the springs 30, which latter rest upon the under faces of the slat-supports, and thus the Slat-supports are in turn supported yieldabiy by the springs 30.

The slat-supports are provided with recesses 33, in which the slats are disposed iiush with the upper faces of the supports, and by means of which recesses they are held properly spaced, said slats being prevented from longitudinal displacement by depending portions 34 at their ends, which lie upon the outer faces of the Slat-supports. As illustrated in Figs. 1 and 2, exible connections, such as chains 35, are attached to the slats in order that they may be kept together when disengaged from their supports.

Additional posts 3G and 37 are connected with the side rails 17 and 18 intermediate their ends, and these posts 36 and 37 are in all respects the same in construction and arrangement as the head and foot posts, with the exception that they do not extend above A third slat-support 38 is disposed with its ends in slots in theinuer faces of theV posts 36, and the ends of this support lie upon helical springs within the posts in the same manner as above described.

In the present structure both the slats and the slat-supports are formed rigid, and thus, if a Weight be placed upon the bed, when the mattress is in place the bed will not sink in spots corresponding to the contour of the- The jack may then be rethe position shown in Fig. 2 of the drawings'. It will furthermore be seen that the present structure permits the inclination of the slats to be adjusted to any angle by correspondingly adjusting the jacks, and that when a thick mattress is employed its upper surface can be caused to lie at the same height as would the uppersurface of a thinner mattress.

Then the Slat-supports 3l are raised above the side rails of the bedstead, it is of course necessary to provide a support for the slats intermediate its ends above the support 38, the upward movement of which is limited by the height of the posts 36 and 37. For this purpose'suppleme'ntal supports 40 are provided. There are two of these supplementary supports, each of which is somewhat more than half as long as the support 38. One of the supplementary supports is connected to one side of the support 38 and adjacent one end thereof by means of links 41, while the other supplementary support is connected by means of links il with the opposite side of the support 38 and adjacent the opposite end thereof. Thus the supplementary supports may be swung upwardly to lie above the main support, their lengths being such that when in this position their adjacent ends will overlap. These overlapping ends are transversely perforated, as shown at 46,r andthe perforations of one supplementary support are adapted to aline with the perforations of the other. i/Vhen the perforations are alin'ed, a pin 45 is passed through any two of the alining perforations to hold the two supplementary supports connected and to prevent them falling to their lowered positions. By shifting the pin the altitudes of the supplementary supports maybe changed, as will be readily understood, and by inclining the links of both supplementary supports inwardly said supports are prevented from rotary displacement by pressure of the bed-slats thereon.v The supplemental supports are thus held in `their elevated positions "and the end supports 3l may be correspondingly adjusted. p

It should be noted that the vertical adjustment of the slat or mattress supports (it being understood that in the event that a'spring bed-bottom or mattress is employed it may be arranged directly upon the transverse bars or supports located, respectively, at the head and foot of the bedstead-frame and at au intermediate point thereof) is accomplished by the bodily adjustment of the means whereby these supports are upheld, such means in the constructionillustrated consisting of springs andthe movable members of the jacks, both springs and jacks being housed in the seats or cavities formed by the bores of the hollow uprights of the bedstead-frame, and being held against downward displacement by the casters, of which the'stems are fitted removably in the lower ends of said ores.

It will of course be understood that in praetice the specific structure shown may be va- IOO IIO

eso,4ee s riedand that the invention itself may be applied to any bedstead to which it is adapted and that any desired materials and proportions may be used without departing from the spirit of the invention.
